Kamen Rider Gaim is not supposed to air today, but someone from the official Toei production page posted the summary for the show's 13th episode! The summary & pictures is now not available on the site as of the moment.

A weird disease starts to spread within Zawame City, the people who were attacked by the Inves are infected and modern medical technology cannot cure this. The blame is now on the Beat Riders who utilize the Inves during Inves Games. Even so, Kouta still transforms to protect the people when he needs to.

At the start time, Yggadrasill contacts Pierre. On the other hand, Hase, whose belt is destroyed, has his friends abandoning him, starts to feel frustrated as he tries to suppress his desire of getting stronger...

This episode will also mark the first appearance of Kamen Rider Gaim Banana Arms. The episode is set to premiere on January 12, 2014.

His belt is destroyed, his friends are abandoning him and he wants to become stronger....somehow I get the feeling that he will join Yggdrasill and become Kamen Rider Sigurd. Maybe I'm wrong, who knows.
